Reading the user manuals for g6 and gx7...they are rather "dumbed down". No mention of touchscreen use for focus point movement while EFV is used. Also no real info on EVF gain.

All those things are there.

There are two different manuals. A basic one and a 350+ page Advanced Feature manual. If you google it you can find PDFs on the UK web site and download them. I put them on my iPad where I can do searches and make bookmarks for specific things. There are plenty of crap features (scene modes, in-camera editing, etc.) you'll probably avoid, so the manual gets much thinner without them.
